Automated thresholding in radiographic image for welded joints
(Taylor & Francis, 2012)
Automated detection of welding defects in radiographic images becomes non-trivial when uneven illumination, contrast and noise are present. In this paper, a new surface thresholding method is introduced to detect defects ...
Automated identification of exudates and optic disc based on inverse surface thresholding
(Springer Science+Business Media, LLC., 2012)
This paper presents a new approach to detect exudates and optic disc from color fundus images based on inverse surface thresholding. The strategy involves the applications of fuzzy c-means clustering, edge detection, otsu ...
Circular discontinuities detection in welded joints using Circular Hough Transform
(Elsevier B.V., 2007)
Conventional radiography is one of the common non-destructive testing which employs manual image interpretation. The interpretation is very subjective and depends much on the inspector experience and working conditions. ...
Various Recognition approach in human faces
(Universiti Teknologi Petronas (UTP), 2005-12-01)
In this paper, we review researches on human faces from aspect offace recognition and face detection. Face emotion recognition are also reviewed. The study of human faces has much assistance on computer vision and machine ...
Detection of coconuts location using separability filter and Hough Transform
(Kolej Universiti Kejuruteraan Utara Malaysia, 2005-05-14)
In this paper, we develop a technique to determine coconuts location using
separability filter and Hough transform method. Our research involves two sequential steps for solving the coconuts detection and recognition. The ...
Object detection using circular hough transform
(Science Publications, 2005)
In this study we propose a new system to detect the object from an input image. The
proposed system first uses the separability filter proposed by Fukui and Yamaguchi (Trans. IEICE
Japan J80-D-II. 8, 2170-2177, 1997) to ...
Object detection using geometric invariant moment
(Science Publications, 2006)
Geometric moment invariant produces a set of feature vectors that are invariant under
shifting, scaling and rotation. The technique is widely used to extract the global features for pattern
recognition due to its ...
A comparison of circular object detection using Hough transform and chord intersection
(Institute of Eelectrical and Electronics Engineering (IEEE), 2007-07)
In this paper, the circular Hough transform (CHT) and the chord intersection have been used to find the circular object in the feature extraction process. The chord intersection technique does not require any gradient ...
Multiple objects detection using Separability Filter and Circular Hough Transform
(Kolej Universiti Kejuruteraan Utara Malaysia, 2006-06-15)
In this paper we propose a new system to detect the object from an input image. The proposed system first uses the separability filter proposed by Fukui and Yamaguchi to obtain the best object candidates and second, the ...
Background correction using average filtering and gradient based thresholding
(Universiti Teknikal Malaysia Melaka, 2016)
Segmentation process on the image with illumination and contrast variation problem is a very challenging task. This problem can reduce the effectiveness of segmentation result. Therefore, the implementation of the proposed ...
